Ergonomic case for 3x4 or 4x4 membrane keypad to be used for 3D Printer Controls. All parts were printed in ABS except for KeypadBottom printed in TPU for grip. Print each file once and assemble. I'm using this connected directly to the Raspberry Pi GPIO pins with no additional electronics. I wrote an Octoprint plugin to interface with my printer, but my Python skills are limited and do not have full customization built into the plug-in yet. If you would like a pre-release of the plugin or would like to help put the finishing touches on the code shoot me a message.
